Arkadiusz,
Split[z,#1<=3 && #2<=3 || #1>3 && #2>3 &]
gives the result you are after.
The test in the 2nd argument should result in true when subsequent elements
(#1 and #2) should belong to the same sublist.
regards,
Maarten

Hi,
I want to split a list, say
z = {1, 3, 2, 6, 4, 7, 5,1,7};
into sublist of elements that are less or equal 3.
so I want to obtain
{{1,3,2},{6,4,7,5},{1},{7}}
How to do it? Probably by applying Split, but what to put in Test?
Split[z,#<=3&] gives :
{{1, 3, 2, 6}, {4}, {7}, {5}, {1, 7}}
Why 6 was put in first sublist together with 1, 3, and 2 since 6>3 and
should be together with 4 in the second sublist?
Thanks,
Arek
